The U.S. used high-pressure steam engines, whereas the British favored low-pressure
engines. The reason for the American preference for high-pressure steam engines was
that
(a) low-pressure steam engines, though more efficient, were complicated to build and
operate and America lacked skilled labor compared to England.
(b) the high-pressure steam engines used extravagant amounts of wood fuel. The U.S.
abundance of wood compared to Europe made building high-pressure steam engines
cheaper in the U.S.
(c) Americans simply lagged behind technologically compared to England and
continued to use the outdated high-pressure steam engines.
(d) England had patents on the superior low-pressure steam engine and would not allow
other nations to use the technology.
Which of the following statements is supported by the research of economic historians?
(a) Canals and railroads were built with a mixture of private and public enterprise
and financing.
(b) Canals and railroads were built largely without U.S. government participation.
(c) Canals were built with public assistance, but railroads were built with almost
no government assistance.
(d) Railroads were built with public assistance, but canals were built by private
enterprise.
